Improvement in machines for forming plow-handles



NITED STATES PATENT Orifice.

W. A. ELLIS, OF ASHTABULA, OHIO.

Specification forming part of Letters Patent No. 56,736, dated July 31, 1866.

To all whom it 'may concern.-

Be it known that I, W. A. ELLIS, of Ashtabula, in the county of Ashtabula and State of Ohio, have invented certain new and useful Improvements in a Machine for forming the Handles for Flows, Gultivators, &c.; and I do hereby declare that the following is a full and complete description of the construe tion and operation of the same, reference being had to the accompanying drawings, making a partei" this specification, in which- Figure 1 is a plan view of the machine. Fig. 2 is a side elevation. Fig. 3 is an end view.

Like letters of reference refer to like parts in the views.

A represents the frame of the machine, at the upper part of which, on the sides facing each other, 4are guides C secured to the frame. In each of these guides is a groove, c, that wrists projecting from the sides of a sliding frame, B, t and move.

F is a revolving cutter-head on a shaft, b, that has its bearings on the frame, turning in journal-boxes c. On one end of the shaft is a pulley, E, to which the driving-power is conframe, is secured a standard, g, to which a cam,

h, is pivoted. There are wrists e on the side pieces, as indicated by the dotted lines e in Fig. l, that extend into the grooves a in the guides.

The grooves a are curved up a little one side of the cutter-head, as seen at a' in Fig. 2. This is for the purpose of bringing the piece of which the handle is to be formed in contact with the cutters, so that it will be curved out in the desired manner.

The curve a.' in the grooves is formed by means of the top of the groove being curved up and an adjustable piece, I, rounded on the upper side to correspond, put in below and secured by a screw passing through a hole in the frame into the piece.

When it is desired to have the grooves straight the piece I on each side is unscrewed and placed above in the curve, filling it up, making the upper and under side of the grooves straight. It is held in place by the screw being put through a hole in the frame, above the hole for attaching it below, and screwed into the piece, as before. There is a groove, c, round in the cutter-head, and the cutters d are of the same shape, so that the handle will be cut rounding at the same time that it is being curved out.

In the practical use of this machine, a straight strip is taken, of which the handle is to be made, and placed on the sliding lframe, as indicated by the red lines in Figs. l and 2, one end tting into a notch at the end of thev frame, and when the cam h is turned down upon the strip it is held securely in place. The frame is then moved along in the guides, the cutters revolving at the same time, and when it comes to the curve a it will be in such a relation to the cutter-head that the cutters will commence cutting the strip, so as to leave it wide at the end, and as it moves along over the curve it will be curved out in the shape indicated by the dotted lines in Fig. 2, forming a head on the end, and the cutters being curved,I as before stated, the edge will be rounded at the same time.

To round off the other side of the handle at the end the same distance that it is curved out, it is turned over and placed on a rest,

J, put on the frame, as seen in Fig. l, that is rounded on the top to iit into the curve of the handle, and it is grooved out also to receive the rounded edge. The handle is held securely in place `by turning down the cam.

In the guides the pieces I are unscrewed and put in above, as before stated, so that the sliding frame will move in a direct line `under the cutter-head, when the cutters will round the edge of the handle in the desired manner without cutting a curve. The sliding frame is moved to round the handle the desired distance, when it is stopped by the standard g coming against the cross-piece f of the frame.

sire tosecure by Letters Patent, is'

In this manner plow-handles' are formed The groove rtf, made adjustable by the rethe desired shape with the greatest facility, movable piece I, in combination with the slidand the machine is simple and substantial in ing frame B and revolving cutter, arranged its construction. Oultivator-handles or any and operating substantially as described. others requiring a similar shape can be made W. A. ELLIS. in the same way.
